IMPROVEMENT IN PIANO PEDAL-STOOLS.

Specification forming part of Letters Patent No. 146,103, dated December 30, 1873; application led November 12, 1873.

To all whom 'it may concern:

Be it known that I, TRAUG'OTT SPRINGER, of Hunters Point, in the county of Queens and State of New York, have invented an Improved Pedal-Stool for Pianos, &c., of which the following is a specification:

Figures l and 2 are transverse sections of my improved pedal-stool for pianos, Cro. Fig. 3 is a side elevation of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to produce an improved attachment, whereby children and shall persons may be enabled to reach the pedals of pianos, melodeons, &c., with their i'cet. My invention consists in the construction of a stool which carries one or more treadles, from each of which a sliding rod extends downward, a spring being' under the treadle to hold it up.

In the accompanying drawing, the letter A represents a stool, made of suitable size and style, of wood or other material, and preferably constructed of two end boards, 'a a, and a top piece, b, as shown in Fig. 3. Upon the top piece are pivoted a suitable number of trcadles, B B, under each of which a rod, D, is arranged in a vertical or slightly inclined position, the rod being connected, or at least in contact with, its treadle. By means of a spring, d, each treadle is held up in the position indicated in Fig. 2; but when the person, with the feet or otherwise, presses yupon the treadle, the spring will yield and allow the treadle to move the rod D downward. For

proper guidance, I have the rod D provided with a projecting pin, e, that extends through a slot in a brace, j", ofthe stool, as shown 5 but this guide-connection may not be necessary, if the top board Z) of the stool is made suiciently thick, or otherwise constructed with proper guidings for the rod.

Then the stool is to be used it is so placed beneath the piano or melodeon, or other instrument on which it may be-useful, that the lower end of each rod D comes directly over the pedal of the piano, so that when a person presses on the treadle B the pedal over which the same is arranged will thereby be affected in the desired manner. In this way children will be permitted to use the pedal attachments of the musical instruments, and to commence studying the use thereof at an early age.

In order to adapt the stool to children, or small persons of varying sizes, the end pieces a a may be made eXtensible and contractible, and the rods D may also be made eXtensible and contractible in suitable manner, for substantiall y the same purpose, and also for adapting the same stool to instruments having their pedals arranged at varying heights.

In some cases, it may be desirable to make the stool with but one treadle, B, to connect with but 011e pedal of the musical instrument; and I do not coniine myself to any number of treadles arranged thereon.

I claim- In a pedal-stool containing the treadle B, sliding rod D, and spring d, the guidebar f, constructed and arranged substantially as shown and described.

TRAUGOTT SPRINGER.
